EXAM 2
Darwin used the term "natural" selection, which he chose in contrast
to _____.
a) neutral selection
b) directional selection
c) artificial selection
d) stabilizing selection - CORRECT REPLY>>>>>>-c) artificial
selection
The Hardy-Weinberg Principle helps identify evolutionary forces that
can change gene frequencies in populations. This model assumes
each of the following except:
a) random mating
b) random mutations
c) large population size
d) no immigration
e) similar fitness among genotypes - CORRECT REPLY>>>>>>-b)
random mutations
, Clausen, Keck and Hiesey used a _____ experimental design.
a) common garden
b) reciprocal transplant
c) laboratory-based
d) greenhouse-based - CORRECT REPLY>>>>>>-a) common
garden
Briefly, the logic motivating a common garden experimental
design is: A similar environment means that differences in
phenotypes are not due to environment variation. Hence any
differences in phenotypic traits will be due to differences in
genotype.
a) True
b) False - CORRECT REPLY>>>>>>-a) True
To be considered different ecotypes, two populations must differ in:
a) the amount of phenotypic plasticity they exhibit.
b) their genotypes which in turn causes differences in the
adaptations found in each population. - CORRECT
